I placed a 600 order for Christmas cookies for my job. I placed it in November when they were open. Now they are closed. No website. No number. No Facebook. No contact with them. They didn t refund me or call to tell me they were closing. I went there and saw someone in the building when it was closed and banged on the door. The guy didn t come to the door. I m definitely taking this up with the law and suing.
